We’ve heard recent concerns from Whitehorse residents about noise from our diesel generators and want to share an update on the noise mitigation solution we are working to implement.
In Yukon, thermal resources such as diesel and liquefied natural gas (LNG) continue to play an important role in meeting winter peak demand and ensuring reliable power year-round.
To better understand and address noise at the Whitehorse Rapids Diesel Facility, we have engaged engineering firms over recent years to monitor sound levels, identify operational noise sources, and evaluate mitigation options. Based on this work, we submitted an environmental monitoring and noise mitigation plan to Environment Yukon in 2025 and are now advancing an engineered solution to reduce facility noise.
The proposed solution involves replacing the exhaust silencers on the facility’s four older diesel units with newer, more effective models. This proposal is currently under review by Environment Yukon.
In the meantime, we have issued a request for proposals (RFP) to move the project forward. Because the solution requires custom design and fabrication rather than an off-the-shelf product, a more detailed timeline will be available once procurement is complete. Our goal is to have the solution installed and operational before December 31, 2026, in accordance with our air emissions permit.
We appreciate the ongoing dialogue with the community and will continue to keep the public informed. We also plan to host a meeting with Riverdale residents in the coming months to provide an opportunity for questions and discussion about this work.
At the Faro Diesel Facility, we are developing a new noise modelling report and updating the existing noise management plan, as required under our air emissions permit.
